Leading up to the tournament, Fish broke the news of his plans on Twitter:
Some members of the tennis world took to Twitter after hearing the news, including the United States Tennis Association:
With a tournament packed full of stars, the U.S. Open's account is certainly looking forward to Fish's appearance:
Per the AP, Fish has only competed in one tournament since August 2013, losing in the first round of the BNP Paribas Open in March of this year. He is going to use a protected ranking in order to enter the U.S. Open, beginning on Aug. 31.
Problems with anxiety that he has battled since March 2012 forced Fish out of tennis, derailing a career that saw him rising through the ranks, reaching as high as seventh in the world in 2011.
The 33-year-old has never won a major in his career, reaching the quarterfinals in the Australian Open, U.S. Open and Wimbledon but no further. One of the tournaments Fish will be competing in before the U.S. Open, the Atlanta Tennis Championships, is one of his most successful settings, winning two titles in his career.
